This method is used to create an instance of an ispec. The session ID and the name of the ispec are passed as parameters. The system creates an instance of the ispec and “recall” it resulting in the ispec’s Construct() method being executed. An object referred to as a GenericClass object is returned. This object is used to pass information between a client and an ispec. It contains the values of all ispec fields, plus status line messages, error messages, etc.
